An explicit procedure is given to obtain the exact maximum likelihood estimates of the parameters in a regression model with ARMA time series errors with possibly nonconsecutive data. The method is ...

Semiparametric regression models are very useful for longitudinal data analysis. The complexity of semiparametric models and the structure of longitudinal data pose new challenges to parametric ...

Envelope Model: A statistical framework that identifies and utilises a subspace containing material variation to improve efficiency in parameter estimation during multivariate regression.

We use a procedure called multilevel regression and post-stratification (MRP), which is a fancy way of describing how it combines the information described above, and blends data about both ...
